SHEET-METAL CLEANING, WASHING, AND DRYING MACHINE.

SPECIE-'rennen forming part ef Letters Patent No. 352,986, dated November 23,1886.

Application filed September lo, 1885. Serial No. 177,228. (No model.)

To all whom it may concern: Y

B e it known that I, WILLIAM WAKELY, of Taunton, in the county of Bristol and Commonwealth of Massachusetts, have invented a new and useful Sheet-Metal Cleaning, Washing, and Drying Machine, of which the fol lowing is a full and exact specification.

My invention relates to a machine for cleaning sheet metal; and it consists of the combination of a set of smoothing and feeding rolls with a set of scouring-rolls provided with water-pi pes for wetting their surfaces, and a set of wiping rolls, whereby I automatically smooth, wash, and dry sheets of metal prepatory for the market.

In the accompanying drawings, Figure l is a side elevation of myr new machine on the side on which I place the pulley connected with the prime power. Fig. 2 is a vertical sectional elevation on the line x x of Fig. 3. Fig. 3 is a plan view of the same. Fig. 4 is an elevation of the opposite side ofthat shown in Fig. l, with the pulleys P2 P3 left 0E.

rIhe frame A of my new machine, which carries the three sets of rolls D D, E E, and F F, rests on supports B B, which vstand in a vat or base, C. To support and guide the sheets in. their passage through the rolls Iuse the racks G Gr'l G3.Q The set of rolls D D, which I preferably make of iron, or any suitable metal, act as smoothingand feeding rolls and deliver the, sheets to the scouring and cleaning rolls E E, which are wooden cylinders covered, preferably, with cocoanut matting tacked on,

though ordinary burlaps or any other suitable' material would do. Ihe rolls F F consist of wood eovered,preferably',with soft rubber, and have the double function of drawing the sheets through the eleaningfrolls E E and of wiping them dry.

The arrows in Fig. 2 show the direction in .which each of the rolls moves when the machine is in operation.

' constantly wet with water by means of the two parallel pipes HHZ, which have aseries of small holes, h h, on their under side in such a position that the water runs out onto the rolls just above their center, as shown in Fig. 2. AThe water is fed to the pipes H H2 through' I keep the rolls E E.

the supply-pipe H3, and is discharged, first, into the vat C C2, and then through the wastepipe H1* H5. 'Ihe pressure or biterequired for the rolls D D is obtained by the weights W W, acting through rods RVR, on the ends of the levers L L (which are pivoted' on the uprights R2 R2, rising'from the frame of the machine) upon the lever-supports :resting on r the bearings of the upper` roll D. Each set of rolls is journaled in the frame of the machine, as .shown in Figs. 1 and 4. The prime power is exerted through the pulley P', P being a loose pulley. same shaft as the pulley P', is geared-to the wheel KVS on the shaft of the upper roll E, and to the wheel Il on the shaft of the lower roll D, as shown in Fig. I. On the other end of the shaft of the lower roll D is the pulley P2 and the wheel W5, which is geared to the lwheel W6 on the shaft of the upper roll D.

The shafts of the rolls F F have geared wheels W7 WS, and are operated through the pulley P3 on the shaft of the lower roll F, bythe belt B2.

I make the frame of the machine preferaably of cast-iron and the vats of the same material.

Vhile this machine can be in'ade any size,

The wheel WZ, on the I preferably place the sets of rolls D D and F F about forty-two inches apart and make the rolls twenty inches in length, as the usual dimensions of sheeting metal of copper and composition are fourteen by forty-eight inches. The diameters of the rolls may vary, but are in the proportions shown in Fig. 2. chine of these proportions the upper vat may be six inches deep and the lower one three.

In operating the machine the sheets are fed from the rack or table G to the rolls D D, and they are then carried through therolls, as described. The rolls E E, as they revolve with the aid ofthe water, scour and wash the sheets, the rolls F F wipe and dry them. if

What I claim is` 1. In asheet-metal smoothing,washing, and drying machine, a set of smoothing and feeding rolls, D D,provided with adjustable pressure-weights, and a set of scouring-rolls geared D D7 in combination with a, set of dryingrolls geared to-run in an opposite direction from `the scouring-rolls, with a supportingfrarne, substantially as described.

2. A sheetqnetal smoothing7 Washing, and drying machine consisting 4of a, frame, A, vets C C2, pipes H2 H2 H* H5, and a set of feedng-1oils, D D, scouring-rolls E E, and:

Wiping-ro11s F F, all arranged and operated substantially as described.

In Wit-ness whereof I have hereunto set my hand.
